FIM SPEEDWAY WORLD CHAMPIONSHIP BIKE SPEC

Anatomy of a speedway bike

Speedway bikes are completely unique, they are 500cc, have a single fixed gear and no brakes! Bikes are differentiated by the engines used, the rear wheel sprockets and the gear ratio chosen. All of this is dependent on the size of the track and racing conditions. They must weigh a minimum of 77kgs to adhere to FIM standards. Pure methanol is used to fuel the bikes, to ensure a higher compression ratio which results in a higher engine power output.
